//jQuery操作cookie的插件,大概的使用方法如下:(1)设置cookie的值  example $.cookie(’the_cookie’, ‘the_value’);(2)新建一个cookie 包括有效期 路径 域名等  example $.cookie(’the_cookie’, ‘the_value’, {expires: 7, path: ‘/’, domain: ‘jquery.com’, secure: true});  (3)新建cookie  example $.cookie(’the_cookie’, ‘the_value’); (4)删除一个cookie  example $.cookie(’the_cookie’, null);
//jQuery.cookie=function(name,value,options){if(typeof value!='undefined'){options=options||{};if(value===null){value='';options.expires=-1}var expires='';if(options.expires&&(typeof options.expires=='number'||options.expires.toUTCString)){var date;if(typeof options.expires=='number'){date=new Date();date.setTime(date.getTime()+(options.expires*24*60*60*1000))}else{date=options.expires}expires='; expires='+date.toUTCString()}var path=options.path?'; path='+(options.path):'';var domain=options.domain?'; domain='+(options.domain):'';var secure=options.secure?'; secure':'';document.cookie=[name,'=',encodeURIComponent(value),expires,path,domain,secure].join('')}else{var cookieValue=null;if(document.cookie&&document.cookie!=''){var cookies=document.cookie.split(';');for(var i=0;i<cookies.length;i++){var cookie=jQuery.trim(cookies[i]);if(cookie.substring(0,name.length+1)==(name+'=')){cookieValue=decodeURIComponent(cookie.substring(name.length+1));break}}}return cookieValue}};
